 Users  Model Capabilities  Data Availability, Accessibility  Other Model, Data Issues

Nowlin Chair Crop Modeling Symposium November 10-11, 2000

USERS

 Applications for what?

 Who will operate the models?

– Developers – Researchers – Advisors to: • Farmers • Policy makers • Industry – Farmers  Automatic Operation?

Nowlin Chair Crop Modeling Symposium November 10-11, 2000

Model Capabilities

 Actual Yield – Tillage – Pests & diseases – Spatial variability influences – Low inputs  Changes in soils  Environment effects, sustainability  Complex cropping systems (space, time)  Genetic X Environment interactions  Address policy, management, & scientific issues

Nowlin Chair Crop Modeling Symposium November 10-11, 2000

Data Availability, Accessibility

 New measurement methods (e.g., precision agriculture, remote sensing)  New capabilities for data access (e.g. Internet)  New types of data (e.g., genomics)  New technology for processing data (e.g., GIS, optimization techniques)  Balance model capabilities and input needs with data availability – need to continually reassess to match our knowledge with capabilities to apply it – where it is needed

Nowlin Chair Crop Modeling Symposium November 10-11, 2000

Other Model, Data Issues

 Intellectual Property Rights  Modularity for efficient development  Data standards for applications

Nowlin Chair Crop Modeling Symposium November 10-11, 2000

Toward an ICASA Toolkit

 Made possible by –Data standards –Modular development of models, components –Data sets –Willingness of scientific community to share  How to operationalize?

–Internet, CD –Distributed system
